60 years of the laser - from first invention to modern techniques
Lasers have certainly come a long way since the basic chromium-doped ruby examples were invented in 1960.
60 years, this small beam of red light is considered one of the most important discoveries of modern times. But how has it changed from its first invention to now.
Lasers emit a constant beam of light of a specific wavelength. While this wavelength can be slightly engineered, the material used is the main factor in the output wavelength of light.
